Title: Bitumen composition
Inventor: KREMER HENRY AUSTIN FRANCIS LE
IPC: C08L95/00
Filed: 1964-10-14
Abstract: A bituminous composition comprises a bitumen of mineral origin, a halohydrocarbon, preferably a chloroparaffin, and a compound of antimony, preferably the trioxide, which will react with the halohydrocarbon at elevated temperature.  The antimony compound constitutes 2.5-10% by weight of the composition, and the halohydrocarbon 3-10%, i.e. in excess of the amount required to react with the antimony compound.  The chloroparaffin melts between 50 DEG and 100 DEG  C. and has a chlorine content of 40-80%. The composition may also contain 1.5-12% by weight of asbestos and a filler such as fly ash.  The composition may be used to impregnate fibrous mats for use as roofing material.

Filed: 1964-10-26
Abstract: <PICT:1074749/C6-C7/1> An electrically conductive workpiece 12, e.g. mounted in a jig 14, is electrochemically shaped by advancing an electrically conductive tool 20 toward the workpiece, e.g. by a ram 16 moved by a feed mechanism 18, preferably at a constant velocity corresponding to the rate of removal of material from the workpiece, oscillating the tool in the same direction as that of its advance, introducing an electrolyte within the gap 40 between the tool and workpiece, e.g. from tank 34 by a pump 36 via filter 38 and inlet pipe 42, and periodically connecting the tool and workpiece in an electrical circuit, e.g. by power supply 24, cables 26, 28 and switch 30, to make the workpiece anodic in relation to the tool when the tool is spaced from the workpiece less than a given distance.  The electrolyte flow may be interrupted and re-established, e.g. by valve 46 in outlet pipe 44, in synchronism with the tool oscillations respectively before and after the tool reaches and has reached a position of minimum spacing from the workpiece.  The tool may be oscillated by a Piezo-electric crystal 22, an electromagnetic vibrator, a rotating eccentric cam adapted to reciprocate a push rod (see Fig. 2, not shown), or a hydraulically reciprocable piston (see Fig. 4 not shown).

Title: Improvements in and relating to a process and an apparatus for drying air or gases
IPC: F24F3/14
Filed: 1960-12-22
Abstract: 976,801. Drying air; evaporating solutions. C. G. MUNTERS. Dec. 22, 1960 [Dec. 23, 1959], No. 44060/60. Headings B1B and BIL. Air is dried by passing it up through the channels of a contact body 16 in a casing 14, while a solution of a hygroscopic salt, such as lithium chloride or bromide, flows down over the surfaces of the contact body. The air is drawn at the sides of the lower part of the casing by means of a fan 28. The contact body is made up of parallel sheets of water-absorbent material (e.g. cellulose or asbestos, impregnated with phenolic resin), the sheets being corrugated, and interconnected along the ridges of the corrugations. The hygroscopic solution is distributed over the top face of the contact body by a rotating arm 36 which has apertures 38. The arm slowly rotates due to the reactionforce produced as the liquid is sprayed from the apertures. The dried air is withdrawn through duct 30. The solution drips off the lower ends of the contact sheets into tray 40, and is collected in basin 42. This solution has now to be re-concentrated by evaporation of some of the water; and this is achieved in regenerator 12, which also contains a contact body 20, similar to that in the drying-section 14. The solution is supplied, via conduit 54, to sprayer-arm 44 which is slowly moved, by motor 46, over contact body 20 ; and the solution is distributed over the sheets from the apertures 50 in the bottom of the arm. Gas, which is heated by burner 82, is blown through conduit 80 ; and the hot gas rises through the channels between the sheets of the contact body, evaporating water from the solution flowing down the sheets as a thin film. Those sheets which are being momentarily supplied with solution are shut off from the current of hot gas ; for the arm 44 and its attached baffles 52 close the top of the feed-channels. Most of the liquid supplied through arm 44 flows off the sheets before the hot gas comes into contact with it, and at the same time flushes down the concentrated solution and any precipitated salt formed in the previous evaporation period. The concentrated solution is collected in tray 70. This solution is mixed, in conduit 62, with the solution withdrawn from the air-dryer. From the conduit 62 a major part of the liquid is passed through conduit 34 to the air-dryer, while the remainder is passed to the regenerator. The heat supplied to the solution during its regeneration may be recovered in heat-exchanger 64. The hot gas, leaving the top of the regenerator through conduit 84, may be recirculated through conduit 85 ; fresh air being introduced through conduit 86 in order to maintain the combustion in burner 82. Specifications 837,601 and 890,790 are referred to.

Abstract: 1401883 Pipe laying EXXON PRODUCTION RESEARCH CO 25 Sept 1972 [1 Nov 1971] 44186/72 Addition to 1297166 Heading F2P A method of installing a pipe-line riser 29 on an offshore structure 11 extending upwards from a submerged bottom 12 comprises laying a pipeline 17 on the bottom with a free end 19 adjacent said structure, positioning a floating vessel 15 over the pipe-line, connecting at least one flexible tension member 21 between the vessel and the pipe-line and establishing an acute angle between at least one, 25, of such tension members and the longitudinal axis of the pipeline, applying force from the vessel to the pipeline through the tension members so as to lift the pipe-line and at the same time maintain sufficient axial tension in the pipe-line to prevent buckling of the portion no longer resting on the bottom, until the end 19 is at the surface, connecting a riser section 29 to said free end and lowering the pipe-line to the bottom again whilst still maintaining sufficient axial tension to prevent buckling. Subsequently the user section is secured to the structure. As shown the forces are applied through a plurality of vertical tension members 21 and a single tension member 25 arranged at an acute angle to the pipe. In a second embodiment (Figs. 4, 5) the tension members are initially arranged vertically and the vessel moved towards the structure 11 so that all the tension members apply vertical lifting force and a force component in the axial direction of the pipe to maintain the tension therein. Alternatively the tension member may be applied initially so as to form an angle with the pipe. In a further embodiment (Fig. 6) the member applying the axial tension can be arranged to pass around a pulley on the structure 11 or on a boom extending from the vessel.

A pump 12 circulates water in a closed circuit containing the tube walls of a converter hood 1, a collecting drum 11 and an array 13 of cooling heat exchangers AX-FZ, the heat exchangers being provided with a by-pass 14 controlled by a three-way proportioning valve 21. The heat exchanger outlet line and the by-pass terminate in nozzles 20 and 24 which are directed towards each other in a mixing chamber 25. The valve 21 is operated by a controller 27 in response to pressure in the collector drum 11 to maintain pressure in the drum between two limits. If the pressure falls below the lower limit, the controller 27 opens a valve 28 in a steam supply line to a heater 29. As an oxygen lance 6 is lowered to its blowing position, a controller 30 which is responsive to lance position, and time devices 41-45 sequentially energize fans which are located to blow air over heat exchangers of the array 13. The controller 30 also operates a valve 31 in the oxygen supply line to the lance. The valve 21 has a by-pass 34 which is controlled by a valve 33 in response to heat exchanger outlet temperature in order to prevent that temperature falling near to freezing. During an inoperative period of the converter, the valve 33 may be held in its fully open position and the steam valve 28 placed under the control of a temperature responsive controller 32 which is normally responsible for operating the valve 33. Devices may be provided for controlling liquid level in the drum 11 and for preventing opening of the oxygen valve 31 if a sufficient number of heat exchanger fans fail to energize.
